UV MetalMask 732

UV MetalMask 732 was developed to mask metal for surface and cavity protection during acid stripping, machining and air plasma spray operations. It is used for repair and overhaul of turbine engines, blades, vanes and other components. It cures in seconds upon exposure to uv light source. Cured film can be easily removed by incineration at 650*c[1200*F]+.

Product Description

UV MetalMask 732 was developed to mask metal for surface and cavity protection during acid stripping, machining and air plasma spray operations. It is used for repair and overhaul of turbine engines, blades, vanes and other components. It cures in seconds upon exposure to uv light source. Cured film can be easily removed by incineration at 650*c[1200*F]+.

UV cure rate is dependent on many variables, such as; coating thickness, lamp irradiance, distance from the light source and line speed. It is recommended that a radiometer be used to monitor irradiance.Depth of Cure: Measured with an EIT UV Power Puck radiometer :
UV_MetalMask 732 has superior depth of cure for a UV cure coating. Most UV_Mask formulations typically cure to a depth of .6 to 1.3 cm ( ” to ”).

We recommend to employ by curing longer and/or at higher intensities than required for full cure. Customer must determine and qualify and verify the appropriate curing parameters required for their specific application.

Optimizing Performance :
1. Exposure to Ambient and artificial light should be keep to minimum before curing. Dispensing components such as needles, fluid lines should be 100% light blocking, not just UV blocking.
2. Air exhaust system is recommended to vent vapors and dissipate heat during the curing process.
3. oxygen in the atmosphere may inhibit surface cure. Surfaces exposed to air may require higher intensity of UV light (more than 100mW/cm2) to produce a tack free cured film. To reduce oxygen inhibition , you can try flooding the bond area with an inert gas such as nitrogen.
4. Before applying UV masking resin, surfaces should be free form mold release, greases and other contaminants.
5. UV Curing produces heat. If required , cooling fans can be used to reduce heating effect on parts being cured. Parts should be allowed to cool down after uv cure before testing to get accurate results.

Clean UP: Uncured UV masking resin can be removed form equipments and parts with organic solvents. Cured material will be impervious to many solvents and very difficult to remove . Clean up of cured material may require mechanical methods.

Storage & Handling
Avoid exposing the product to high temperatures and minimize exposure to artificial or natural light prior to curing. UV masking resins can polymerize upon prolonged exposure to ambient and other source of lights. Keep it covered when not in use. Shelf Life is up to 1 year when properly stored between 50*f to 90*f in unopened original container.
This product is intended for industrial use only. Avoid Breathign vapors. Avoid direct contact with skin,eyes and clothing.. Wear Impervious gloves. Remvoe materail from skin with soap and water. Do no tuse solvnets to remove material from skin and eyes. Consult Material safety data sheet before use.
